Public repository of the Cosmic Linear Anisotropy Solving System (master for the most recent version of the standard code; GW_CLASS to include Cosmic Gravitational Wave Background anisotropies; classnet branch for acceleration with neutral networks; ExoCLASS branch for exotic energy injection; class_matter branch for FFTlog)
There are at the moment a number of possibly easy-to-fix problems producing warnings and errors during CLASS' build with up-to-date Python (3.11) and requirements (cython v3). This is an issue to gather all three:
Using old setup.py instead of pyproject.yml, and calling setup.py directly --> throws a WARNING, but will fail in the future.
Using the old numpy API --> throws a WARNING, but will fail in the future

Hi all,
There are at the moment a number of possibly easy-to-fix problems producing warnings and errors during CLASS' build with up-to-date Python (3.11) and requirements (cython v3). This is an issue to gather all three:
Using old
setup.pyinstead ofpyproject.yml, and callingsetup.pydirectly --> throws a WARNING, but will fail in the future.Using the old numpy API --> throws a WARNING, but will fail in the future
Using cython syntax incompatible with the new cython3 (already reported in https://github.com/lesgourg/class_public/issues/531, where the workaround of installing
cython<3is proposed, and there is a PR fixing it at https://github.com/lesgourg/class/pull/136, but still not merged intoclass_public).Could we at least get a mini-release where 3 is fixed, while all this is done?
